Y., ASSIGNOR TO R. HOE-8c CO., INC., OF NEW YORK, N. Y., A CORPORATION OF NEW YORK PERFORATING MECHANISM FOR USE IN PRINTING MACHINES Application led December 21, 1929. Serial No. 415,818.

This invention relates to folders for printing machines of the class used for printing magazines and similar products, and Vis adapted to perforate these products so they 5 may conveniently be bound in a loose leaf binder.

It is an especial object of the invention to provide a perforating-mechanism that may be incorporated in the folder of a printing 1o machine, and so arranged that without arresting its motion, the printed product can be perforated while it is being forwarded from the folding mechanism to the delivery.

It is also an object of the invention to provide a perforating mechanism for incorporation in a printing machine folder, that will be simple, durable and relatively inexpensive in construction, as well as convenient, practical, serviceable and eiiicient in use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts, and in the details of construction hereinafter described and claimed, it being understood that various changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein:

Figure 1 is an end view of a portion of a a5 folder adapted for use with a printing machine, showing incorporated therein, the perforating mechanism that is the subject of the invention;

Figure 2 is a sectional view of a portion of the folder with certain parts broken away, showing the perforating mechanism and the co-acting parts as they appear on the line 2-2 of Figure 1 and in the direction of the arrow.

Figure 3 is a view showing certain parts of the perforating mechanism drawn to a larger scale than in Figure 1, to better illustrate its operation, and showing the position of the parts when a sheet is approaching; and

Figure 4 is a view similar to Figure 3 showing the position of the parts just after the product has been perforated. j

Referring to the drawings, 11 and 11 indicate side frames of al Vfolder for a web printing machine, that carry bearings for the shafts of the various cylinders and rollers shown.

In the embodiment of the invention herein disclosed, a portion of a folding cylinder is w shown at 12, having jaws 12 into which a product comprising one or more pointed sheets is pressed by the usual form of tucking blade. A transfer cylinder is indicated at 13, having grippers 14, adapted to receive a folded product from the folding cylinder 12, and transfer it to the running tapes 15 and 16, by which it is forwarded to the perforating mechanism that is the subject of the present invention, and which is generally ingm dicated at 17. Y

The perforating mechanism which is arranged on a movable support, includes a carrier frame 18 as shown in Figure 2, that is fitted to slide in guides 19 and 19, secured 75 to the side frames 11 and 11. Dies indicated at 2O are secured to the carrier, and co-acting punches 21,- are secured to a punch holder 22, that is fitted to slide vertically in suitable guides in the carrier side frames 23 and 23, that are fixed to the carrier frame 18. Lugs 24 and 24 are formed on the punch holder and are connected by links 25 and 25', with arms 26 and 26', secured to a rock shaft 27, rotatably supported in the carrier side frames 23 and 23. An arm 28 carrying a roller 29, is secured to one end of the rock shaft 27 and to the other end is secured an arm 31, pivotally connected to one end of a rod 32, the other end of which is arranged to slide in the carrier frame 18. A spring 33, bears against a collar 34, secured to the rod 32, and acts to bias the rock shaft 27 in a counter clockwise direction, as shown in Figures 1, 3 and 4. A stop 35, is located to engage a lug 31 on the arm 31 and limit the motion of the roclr shaft 27. A second roclr shaft 36, is rotatably supported in the carrier side frames 23 and 23 and secured thereto are arms 37, 38 and 38. The arm 37 is connected to a spring 39, the other end of which is secured to a stud 41 fixed to the side frame 23, and thus biases the rock shaft 36 in a clockwise direction as shown in Figures 1, 3 and 4.

The arms 38 and 38 carry supports 42 for registering gages 43 and presser fingers 44. A link 45, is pivotally connected to the arm 38 and to an arm 46 that is rotatable on the shaft 27, and which carries a roller 47.A

Power from any suitable source is applied to the main drive shaft 48 to which the cylinder 12 is secured. A gear 49 is also secured to the shaft and meshes with a gear 51, secured to the shaft 52, which carries the transfer cylinder 13. A gear 53 is also secured to the shaft 52, and meshes with a gear 54, secured to the shaft 55, to which the gear 56 is secured. This gear meshes with an idler 57, rotatably supported on a stud 58, secured to the frame 11. The idler 57 also meshes with a gear 59 secured to the clutch member 60 that is loose on the shaft 62. The mating member of the clutch 61 is fitted to slide on a key 61 secured to the shaft 62, and a bracket 63 secured to the frame 11 provides an outer support for the journals of the several shafts as shown. A cam 64, is secured to the shaft 62, and is engaged by a roller 65, on the connecting rod 66, that is pivotally secured to the arm 67, which is in turn secured to the rock shaft 68. The arms 69 and 69, are secured to the rock shaft 68, and links 71 and 71 are pivotally connected to the lugs 72, formed on the carrier frame 18.r It will thus be understood that rotation of the shaft 62, will cause a reciprocating motion of the carrier frame which carries the perforating mechanism. Y

A cam 73 is secured to the shaft 62 and is engaged by a roller 74, on the rod 75, the opposite end of which is pivotally connected to an arm 76, secured to a rock shaft 77, rotatably supported in the side frames 11 and 11. An arm 78 is secured to the shaft 77 and engages the roller 29. Similarly, an arm 79 is secured to the shaft 77 and is adapted to engage the roller 47.

It will be understood that when the perforating mechanism is moved from the position shown in Figure 3 to the position shown -in Figure 4 that the lower surfaces of the arms 78 and 79 will act as ca-ms on the rollers 29 and 47, and turn theshafts 27 and 36, thus operating the registering gages and the punches. It will also be understood that when the arms 78 and 79 are raised under the influence of the cam 73, that the rollers 29 and 47 will not be pressed down.

The tapes 15 pass around the cylinder 13 and the cylinder 81, the roller 82 and guide sheaves 83 and 84, and the tapes 16 pass around the cylinder 85, the cylinder 81 and guide sheaves 86. Power is communicated to the cylinder 81 by means of the gear 59 which meshes with idler gear 87, which in turn meshes with gear 88, secured to the shaft 91, which carries the cylinder 81. The gear 89 also meshes with gear 92 secured to the roller 82. Guide sheaves 83 and 86 are supported on arms 93 and 94 which are adjustably secured to shafts 95 and 96 thereby providing means for tigatening the tapes. Sheaves 84 are fitted to turn freely on the shaft 77.

A packer box form of delivery is indicated generally at 97 with the packer 98, having arms 99, and arranged to slide in ways 101. A link 102 is pivotally secured to the packer 98 and also to an arm 103 that is secured to a rock shaft 104. An arm 105 is also secured to this shaft and pivotally connected to one end of a rod 106, the other end of which is connected to a crank pin 107, on an arm lation to each other.

In operation, assuming the clutch members 60 and 61 are in engagement, a product receives its first fold when it is taken by the `jaws 12 which transfer it to grippers 14. It is then engaged by the tapes 15 and 16, released by the gripper-s, and carried to the perforating mechanism. As the product advances, it is registered by the registering gages 43 and held in place by the presser fingers 44. At this time, the carrier 18 will be advancing at the same speed at which the product'is moving, and the rollers 29 and 47 are being acted upon by the cam surfaces of the arms 78 .and 79. Thus when the carrierreaches the position shown in Figure 4, the product will have been perforated. Further motion of the carrier withdraws the punches and moves the registering gages away from the product, the motion'of which is then controlled by the tapes, which carry it forward and deposit it in the delivery box 97. Packer fingers 99 then move forward and push it ahead so as to leave'space for the neXt product following.

During the return stroke of the carrier 18, the arms 78 and 79 are raised out of the path of the rollers 29 and 47 and hence the registering gages and the punches are not operated. The various parts again reach the positions shown in Figures 1 and 3 before the next product arrives and the operation then is repeated.

It will be seen that by disengaging the clutch member 61, the shaft 62 will be silenced and with it the means for operating the perforating mechanism, although the tapes and the delivery mechanism will function as before.

From the above, it will be understood that a mechanism has been provided that may be ice incorporated in the folder of a printing machine to perforate a product while it is being forwarded from the folder mechanism to the delivery and without arresting its motion.
